To resolve the issue please follow one of these directions:
- If there is only a few content items, one can just republish those items in the CMS.
- If there a lot of content items, then one can either:
- Use the ContentManager to retrieve and republish these content items.
- Use the database SP named cms_UrlAliasRegenAll to regenerate all auto aliases.
NOTE - We always recommend before any API or SQL to make a backup of database.
